L.A. Now Live: Latest on Venice crash suspect

A Colorado man was charged with murder and other crimes for allegedly driving his car into pedestrians on the Venice boardwalk Aug. 3, 2013. Nathan Louis Campbell faces a murder charge, 16 counts of assault with a deadly weapon and 17 counts of hit-and-run.

The 38-year-old suspect accused in Saturday's deadly hit-and-run on the Venice boardwalk had a history of arrests in Colorado and Florida, including an April 2008 reckless driving arrest involving alcohol in Panama City Beach, Fla.

Times reporter Hailey Branson-Potts will join L.A. Now Live at 9 a.m. Tuesday to discuss the latest on the investigation.

Witnesses say Nathan Louis Campbell appeared to deliberately target pedestrians as he tore through crowded Ocean Front Walk in a Dodge Avenger, sending tourists and vendors diving for cover. Alice Gruppioni, a 32-year-old Italian tourist who in California on her honeymoon, was killed. Sixteen others were injured.

Authorities said Campbell turned himself in to Santa Monica police shortly after the incident and was arrested on suspicion of murder. Sources familiar with the investigation said he made statements at the time of his arrest implicating himself but did not elaborate on what specifically he had said.

He came to Los Angeles less than a month ago after purchasing the car from a dealership in Littleton, Colo.

Campbell lived in Hollywood nearly two decades ago, staying on and off for a few months at Covenant House, which provides services and housing for homeless youth. It's unclear how he spent the years in between. Aside from a string of petty crimes in Colorado and Florida, little is known about him.

Public records showed Campbell had lived in Georgia, Florida and most recently Colorado. The records also showed that Campbell had a history of arrests in both Denver and Florida.

Sources familiar with the investigation said detectives were focused on the months immediately leading up to Saturday's incident and whether any major life events could help explain his actions.

The sources said Campbell had a history of drug and alcohol addiction, but did not elaborate. They added that he had been clean and sober for some time but had recently relapsed.
